Psoriasis and vascular disease-risk factors and outcomes: a systematic review of the literature

Secukinumab in Pediatric Patients with Plaque Psoriasis: Pooled Safety Analysis from Two Phase 3 Randomized Clinical Trials

BACKGROUND

Plaque psoriasis affects ~ 1% of the pediatric population, negatively impacting quality of life. The efficacy and safety of secukinumab in pediatric patients with moderate to severe or severe chronic plaque psoriasis have been established in two pivotal phase 3 trials (open-label, NCT03668613; double-blind, NCT02471144).

OBJECTIVES

The aims were to report the pooled safety of secukinumab up to 52 weeks from two studies in subgroups of pediatric patients stratified by age and bodyweight, and to present, alongside the pediatric data, the pooled safety data from four pivotal adult secukinumab trials.

METHODS

The safety of secukinumab was evaluated in subgroups of pediatric patients defined by age (6 to < 12 and 12 to < 18 years) and bodyweight (< 25 kg, 25 to < 50 kg, and ≥ 50 kg) in the pooled population. Patients received secukinumab low dose (LD; 75/75/150 mg), secukinumab high dose (HD; 75/150/300 mg), placebo, or etanercept (0.8 mg/kg). For safety analyses, data were pooled from the pediatric studies NCT03668613 and NCT02471144, and presented alongside the pooled data from four adult pivotal studies (NCT01365455, NCT01636687, NCT01358578, NCT01555125).

RESULTS

A total of 198 pediatric patients (overall exposure: 184.6 patient-years [PY]) and 1989 adult patients (1749.5 PY) receiving secukinumab up to week 52 were included in this analysis. At week 52, the incidence of adverse events (AEs) was lower in the lower age and bodyweight subgroups. The AEs reported within these subgroups were consistent with the overall AEs reported in this analysis. Overall, exposure-adjusted incidence rates for treatment-emergent AEs were lower in the secukinumab-treated pediatric pool (198.8/100 PY) compared with the etanercept (266.3/100 PY) and adult pools (256.1/100 PY). Up to 52 weeks, the incidence rates of the AEs in the secukinumab-treated patients in the 6 to < 12 years subgroup and 12 to < 18 years subgroup were 167.7/100 PY and 214.7/100 PY, respectively. Similarly, incidence rates of the AEs in the secukinumab-treated patients in the < 25 kg, 25 kg to < 50 kg, and ≥ 50 kg subgroups were 177.3/100 PY, 192.5/100 PY, and 206.8/100 PY, respectively. Nasopharyngitis was the most frequently reported AE in secukinumab-treated pediatric patients across age (< 12 years: 11.8/100 PY; ≥ 12 years: 42.4/100 PY) and bodyweight (< 25 kg: 22.8/100 PY; 25 kg to < 50 kg: 19.0/100 PY; ≥ 50 kg: 43.0/100 PY). Of the 198 secukinumab-treated pediatric patients, one reported nail Candida, one reported skin Candida, and two reported vulvovaginal Candida. Transient and mostly mild events of neutropenia were observed with secukinumab, none leading to study treatment discontinuation. No incidence of treatment-emergent anti-drug antibodies was reported in pediatric patients treated with secukinumab.

CONCLUSIONS

Secukinumab was well tolerated in pediatric patients with moderate to severe and severe plaque psoriasis across age and bodyweight subgroups. The overall safety profile of secukinumab in pediatric patients was consistent with that of adult patients.

Association between psoriasis and peripheral artery occlusive disease: a population-based retrospective cohort study

Introduction

Psoriasis (PSO) is a chronic skin condition that affects a variety of disorders, especially the cardiovascular system. This study investigated the association between PSO and peripheral arterial disease (PAOD).

Methods

A retrospective cohort study design was carried out between 2000 and 2018. The exposure subject was a newly diagnosed PSO. The diagnosis of PSO was never elaborated as a comparison subject. Balanced heterogeneity of the two groups was used by propensity score matching. The cumulative incidence of PAOD between the two groups was performed using Kaplan-Meier analysis. The Cox proportional hazard model was used to measure the risk of PAOD risk hazard ratio.

Results

After matching the 1: 1 propensity score, 15,696 subjects with PSO and the same number of subjects without the diagnosis of PSO were recruited. The PSO subject had a higher risk of PAOD than the non-PSO subject (adjusted HR = 1.25; 95% CI = 1.03-1.50). In the 40-64-year-old subgroup, the subject of PSO exhibited an increased risk of PAOD than the subject without PSO.

Conclusion

Psoriasis is associated with an increased risk of peripheral arterial disease and curative care is necessary to reduce the risk of PAOD..

Identifying and managing psoriasis-associated comorbidities: the IMPACT research programme

Background

Psoriasis is a common, lifelong inflammatory skin disease, the severity of which can range from limited disease involving a small body surface area to extensive skin involvement. It is associated with high levels of physical and psychosocial disability and a range of comorbidities, including cardiovascular disease, and it is currently incurable.

Objectives

To (1) confirm which patients with psoriasis are at highest risk of developing additional long-term conditions and identify service use and costs to patient, (2) apply knowledge about risk of comorbid disease to the development of targeted screening services to reduce risk of further disease, (3) learn how patients with psoriasis cope with their condition and about their views of service provision, (4) identify the barriers to provision of best care for patients with psoriasis and (5) develop patient self-management resources and staff training packages to improve the lives of people with psoriasis.

Design

Mixed methods including two systematic reviews, one population cohort study, one primary care screening study, one discrete choice study, four qualitative studies and three mixed-methodology studies.

Setting

Primary care, secondary care and online surveys.

Participants

People with psoriasis and health-care professionals who manage patients with psoriasis.

Results

Prevalence rates for psoriasis vary by geographical location. Incidence in the UK was estimated to be between 1.30% and 2.60%. Knowledge about the cost-effectiveness of therapies is limited because high-quality clinical comparisons of interventions have not been done or involve short-term follow-up. After adjusting for known cardiovascular risk factors, psoriasis (including severe forms) was not found to be an independent risk factor for major cardiovascular events; however, co-occurrence of inflammatory arthritis was a risk factor. Traditional risk factors were high in patients with psoriasis. Large numbers of patients with suboptimal management of known risk factors were found by screening patients in primary care. Risk information was seldom discussed with patients as part of screening consultations, meaning that a traditional screening approach may not be effective in reducing comorbidities associated with psoriasis. Gaps in training of health-care practitioners to manage psoriasis effectively were identified, including knowledge about risk factors for comorbidities and methods of facilitating behavioural change. Theory-based, high-design-quality patient materials broadened patient understanding of psoriasis and self-management. A 1-day training course based on motivational interviewing principles was effective in increasing practitioner knowledge and changing consultation styles. The primary economic analysis indicated a high level of uncertainty. Sensitivity analysis indicated some situations when the interventions may be cost-effective. The interventions need to be assessed for long-term (cost-)effectiveness.

Limitations

The duration of patient follow-up in the study of cardiovascular disease was relatively short; as a result, future studies with longer follow-up are recommended.

Conclusions

Recognition of the nature of the psoriasis and its impact, knowledge of best practice and guideline use are all limited in those most likely to provide care for the majority of patients. Patients and practitioners are likely to benefit from the provision of appropriate support and/or training that broadens understanding of psoriasis as a complex condition and incorporates support for appropriate health behaviour change. Both interventions were feasible and acceptable to patients and practitioners. Cost-effectiveness remains to be explored.

Future work

Patient support materials have been created for patients and NHS providers. A 1-day training programme with training materials for dermatologists, specialist nurses and primary care practitioners has been designed. Spin-off research projects include a national study of responses to psoriasis therapy and a global study of the prevalence and incidence of psoriasis. A new clinical service is being developed locally based on the key findings of the Identification and Management of Psoriasis Associated ComorbidiTy (IMPACT) programme.

Prevalence and severity of coronary artery disease linked to prognosis in psoriasis and psoriatic arthritis patients: a multi-centre cohort study

OBJECTIVES

(i) To estimate the prevalence and severity of coronary artery disease and (ii) to assess the risk of cardiovascular events and mortality, in patients with psoriasis and psoriatic arthritis (PsA) in a large-scale cohort of patients referred to coronary computed tomography angiography (CTA).

METHODS

This was a cross-sectional study with follow-up of 46,022 patients based on data from a Danish national CTA registry. Exposure was defined as psoriasis or PsA. A group of patients without psoriasis, PsA or any other inflammatory disease was used as reference. Cross-sectional primary outcomes were a coronary artery calcium score (CACS) >0 and CACS ≥400, and secondary outcome was obstructive CAD. At follow-up, the primary outcome was a composite endpoint of cardiovascular events and all-cause mortality. All outcomes were adjusted for traditional cardiovascular risk factors.

RESULTS

We identified 1356 psoriasis and 370 PsA patients. The adjusted odds ratio (OR) for psoriasis patients for CACS >0, CACS ≥400 and obstructive CAD was 1.26 (1.10-1.46), 1.25 (1.04-1.50) and 1.14 (0.98-1.33), respectively. For PsA patients, OR for CACS >0 was 1.28 (1.00-1.64). We found a crude hazard ratio (HR) of 1.49 (1.21-1.85) and adjusted HR of 1.14 (0.92-1.41) for the primary outcome in psoriasis patients.

CONCLUSIONS

In this population, both psoriasis and PsA were associated with an increased prevalence of coronary calcification. Psoriasis patients also showed an increased prevalence of severe calcification. Psoriasis patients were at increased risk for cardiovascular events and death, however not after adjusting for the effect of other predictors.

Societal impact for patients with psoriasis: A nationwide Swedish register study

Background

Psoriasis is an immune-mediated chronic inflammatory disease having a significant negative health impact. Psoriasis has societal impact; loss of productivity has been estimated at approximately 10% and it may influence the patient's financial status. Relationships between quality of life, disease severity, and cost of care need exploration. Understanding the disease burden is important for health policy and research allocation. Few studies address the research gaps in socioeconomics, comorbidity, and medication use.

Objective

Observing differences in education, income, employment status, marital status, health care consumption, and drug utilization between patients with psoriasis and matched controls.

Methods

Cohort study following socioeconomics and health care consumption for all psoriasis patients from the Swedish patient register. All individuals with a first diagnosis of psoriasis in outpatient or inpatient care from 2002 to 2013 were followed until death, emigration, or end of the study.

Results

Overall, 109,803 patients were included (mean age 51.2 years, 53% women) and matched with 1.08 million controls. The levels of education and income were similar, but the proportion employed was significantly lower for patients with psoriasis. There was a tendency for fewer patients with psoriasis to be married.

Limitations

Generalizability, lack of primary care diagnoses, and lack of early treatments (available from 2005).

Conclusion

Understanding of the socioeconomic impact of psoriasis is extended by showing reductions in employment.

The Association Between Vascular Inflammation and Depressive Disorder. Causality, Biomarkers and Targeted Treatment

Diabetes, obesity, atherosclerosis, and myocardial infarction are frequently co-morbid with major depressive disorder. In the current review, it is argued that vascular inflammation is a factor that is common to all disorders and that an endothelial dysfunction of the blood-brain barrier could be involved in the induction of depression symptoms. Biomarkers for vascular inflammation include a high plasma level of C-reactive protein, soluble cell-adhesion molecules, von Willebrand factor, aldosterone, and proinflammatory cytokines like interleukin-6 or tumor necrosis factor α. A further possible biomarker is flow-mediated dilation of the brachial artery. Treatment of vascular inflammation is expected to prevent or to reduce symptoms of depression. Several tentative treatments for this form of depression can be envisioned: eicosapentaenoic acid (EPA), valproate, Vagus-nerve stimulation, nicotinic α7 agonists, and agonists of the cannabinoid CB₂-receptor.

Postimplantation Syndrome Is Not Associated with Myocardial Injury after Noncardiac Surgery after Endovascular Aneurysm Repair

BACKGROUND

Postimplantation syndrome (PIS) is the clinical and biochemical expression of an inflammatory response following endovascular aneurysm repair (EVAR), with a reported incidence ranging from 2% to 100%. Although generally benign, some studies report an association between PIS and postoperative major adverse cardiovascular events (MACEs). Nonetheless, the role of PIS in postoperative myocardial injury after noncardiac surgery (MINS) is unknown. This work aims to evaluate the relationship between PIS and MINS in a subset of EVAR patients, as well as assess the impact of PIS in all-cause mortality.

METHODS

All patients undergoing elective standard EVAR between January 2008 and June 2017, and with at least one measurement of contemporary (cTnI) or high sensitivity troponin I (hSTnI) in the first 48h after surgery, were retrospectively analyzed. PIS was defined as the presence of fever and leukocytosis in the postoperative period in the absence of infectious complications. MINS was defined as the value exceeding the 99th percentile of a normal reference population with a coefficient of variation <10%, which was >0.032 ng/mL for cTnI and 0.0114 (female) and 0.027 ng/mL (male) for hSTnI. Patients' demographics, comorbidities, medication, access, and anesthesia were also evaluated.

RESULTS

One hundred thirty-three consecutive patients were included (95.5% male; mean age 75.66 ± 7.13 years). Mean follow-up was 46.35 months. Survival rate was 86.5%, 80.5%, and 57.6% at 1, 3, and 5 years of follow-up, with 2 fatalities at 30 days of follow-up. The prevalence of PIS was 11.4%. MACE occurred in 2.3% of the patients, while MINS was reported in 16.5% of the patients. No association was found between PIS and patients' gender, comorbidities, type of anesthesia, or transfusional support. The type of graft used significantly affected the prevalence of PIS, with all cases reported when polyester grafts were used (P = 0.031). MACE occurred in 2.3% of the patients, while MINS was reported in 16.5% of the patients. PIS was found to be significantly associated with postoperative MACE (P = 0.001), but not MINS. Survival analysis revealed no differences between patients with or without PIS regarding 30-day mortality as well as long-term all-cause mortality. American Society of Anesthesiologists score (hazard ratio [HR] 2.157, 95% confidence interval [CI] 1.07-4.33, P = 0.031) and heart failure (HR 2.284, 95% CI 1.25-4.18, P = 0.008) were found to be independently associated with increased long-term all-cause mortality in this cohort of patients.

CONCLUSIONS

PIS is a common complication after EVAR, occurring in 11.4% of the patients from this cohort. Graft type seems to significantly affect the risk of PIS, since all reported cases occurred when polyester grafts were used. PIS did not influence 30-day or long-term survival and was found to be significantly associated with postoperative MACE but not MINS, suggesting the involvement of different pathophysiological mechanisms.

Interleukin-17 Reduces βENaC via MAPK Signaling in Vascular Smooth Muscle Cells

Degenerin proteins, such as the beta epithelial Na⁺ channel (βENaC), are essential in the intracellular signaling of pressure-induced constriction, an important vascular smooth muscle cell (VSMC) function. While certain cytokines reduce ENaC protein in epithelial tissue, it is unknown if interleukin-17 (IL-17), a potent pro-inflammatory cytokine, directly mediates changes in membrane-associated βENaC in VSMCs. Therefore, we tested the hypothesis that exposure to IL-17 reduces βENaC in VSMCs through canonical mitogen-activated protein kinase (MAPK) signaling pathways. We treated cultured rat VSMCs (A10 cell line) with IL-17 (1–100 ng/mL) for 15 min to 16 h and measured expression of βENaC, p38MAPK, c-jun kinase (JNK), and nuclear factor kappa-light-chain-enhancer of activated B cells (NFκB). IL-17 reduced βENaC protein expression in a concentration-dependent fashion and increased phosphorylation of p38MAPK by 15 min and JNK by 8 h. NFκB was unaffected by IL-17 in VSMCs. IL-17 treatment reduced VSMC viability but had no effect on cell death. To determine the underlying signaling pathway involved in this response, VSMCs were treated before and during IL-17 exposure with p38MAPK or JNK inhibitors. We found that JNK blockade prevented IL-17-mediated βENaC protein suppression. These data demonstrate that the pro-inflammatory cytokine IL-17 regulates VSMC βENaC via canonical MAPK signaling pathways, raising the possibility that βENaC-mediated loss of VSMC function may occur in inflammatory disorders.

Serum homocysteine level, vitamin B12 levels, and erythrocyte folate in psoriasis: A case-control study

Background

One of the most important organ involvements in psoriasis is atherosclerotic cardiovascular disease. Homocysteine is known to have atherogenic properties, but some inconsistency exists in the literature about its probable role as a risk factor of cardiovascular disorder in patients with psoriasis.

Objective

Because of some controversies, we compared homocysteine levels and related parameters of metabolic cycles in patients with psoriasis and healthy individuals.

Methods

This case-control study was conducted on 50 patients with psoriasis and 50 healthy individuals as the controls. Serum homocysteine, vitamin B12 levels, and erythrocyte folate concentrations were checked in all participants.

Results

Mean serum homocysteine, erythrocyte folate, and vitamin B12 levels did not show any significant difference between the two groups (p > .05), but interestingly, in patients with psoriasis, men had a significantly higher incidence of hyperhomocysteinemia and lower levels of erythrocyte folate (p = .14). Overall, there is no significant difference in serum levels of homocysteine and metabolic-related parameters between the case and control group. There was no significant relationship between the severity of psoriasis and the body mass index of patients (p > .05).

Conclusion

Patients with psoriasis had a higher body mass index and higher levels of homocysteine in men. Hyperhomocysteinemia could be a predisposing factor of cardiovascular events, but more evaluations as a part of metabolic syndrome in patients with psoriasis are needed.

The economic burden of psoriasis with high comorbidity among privately insured patients in the United States

OBJECTIVE

To evaluate the impact of comorbidities on healthcare resource use (HRU), and direct and indirect work-loss-related costs in psoriasis patients.

METHODS

Adults with psoriasis (≥2 diagnoses, the first designated as the index date) and non-psoriasis controls (no psoriasis diagnoses, randomly generated index date) were identified in a US healthcare claims database of privately-insured patients (data between January 2010 and March 2017 were used). Psoriasis patients were stratified based on the number of psoriasis-related comorbidities (0, 1-2, or ≥3) developed during the 12 months post-index. All outcomes were evaluated during the follow-up period, spanning the index date until the end of continuous health plan eligibility or data cut-off. HRU and costs per-patient-per-year (PPPY) were compared in psoriasis and non-psoriasis patients with ≥12 months of follow-up.

RESULTS

A total of 9,078 psoriasis (mean age = 44 years, 51% female) and 48,704 non-psoriasis (mean age = 41 years, 50% female) patients were selected. During the 12 months post-index, among psoriasis vs non-psoriasis patients, 71.0% vs 83.0% developed no psoriasis-related comorbidities, 26.3% vs 16.0% developed 1-2, and 2.6% vs 1.0% developed ≥3 psoriasis-related comorbidities. Compared to non-psoriasis patients, psoriasis patients had more HRU including outpatient visits (incidence rate ratios [IRRs] = 1.52, 2.03, and 2.66 for 0, 1-2, and ≥3 comorbidities, respectively [all p < 0.01]) and emergency room visits (IRRs = 1.12, 1.59, and 2.45 for 0, 1-2, and ≥3 comorbidities, respectively [all p < 0.01]) during the follow-up period. Psoriasis patients incurred greater total healthcare costs (mean cost differences [MCDs] = $1,590, $5,870, and $18,427, in patients with 0, 1-2, and ≥3 comorbidities, respectively [all p < 0.01]), and work-loss-related costs (MCDs = $335, $655, and $1,695, in patients with 0, 1-2, and ≥3 comorbidities, respectively [all p < 0.01]).

CONCLUSIONS

HRU and cost burden of psoriasis are substantial, and increase with the development of psoriasis-related comorbidities.

Cardiovascular Risk Markers and Major Adverse Cardiovascular Events in Psoriatic Arthritis Patients

BACKGROUND

Psoriatic arthritis is a chronic inflammatory arthropathy that affects 14%- 30% of patients with skin and/or nail psoriasis, leading to severe physical limitations and disability. It has been included in the group of spondyloarthropathy with which it shares clinical, radiologic, and serologic features in addition to familial and genetic relationship. Beyond skin and joint involvement, psoriatic arthritis is characterized by a high prevalence of extra-articular manifestation and comorbidities, such as autoimmune, infectious and neoplastic diseases. In particular, an increased risk of cardiovascular comorbidity has been observed in psoriatic arthritis patients.

METHODS

A systematic search was performed in the electronic databases (PubMed, Web of Science, Scopus, EMBASE) up until January 2017. Studies were included if they contained data on CV disease and/or risk factors in PsA and each article was then reviewed for quality and clinical relevance. After completing the literature search all screened literature was summarized and discussed in our study group (CaRDDs study group). All literature and comments were included in the systematic review.

RESULTS

The initial search produced 278 abstracts, which were narrowed to 83 potentially relevant articles by preliminary review of the titles and by excluding review articles and case report (n = 195). Thirty articles were deemed ineligible after examining the abstracts. Full texts of the remaining 53 articles were retrieved. The majority of articles excluded were due to only providing data on patients with psoriasis or due to being not relevant to the CV risk in PsA. In the end, 32 articles were deemed eligible for this review.

CONCLUSION

Psoriatic arthritis appeared significantly associated with subclinical atherosclerosis and endothelial dysfunction and, in turn, with an increased cardiovascular risk. Thus, patients with psoriatic arthritis may benefit from a periodic assessment of surrogate markers of cardiovascular risk. This could help to establish more specific cardiovascular prevention strategies for these patients.

Incidental Abdominal Aortic Aneurysm in the Psoriasis Patient: A Case Report and Review of Literature

Background

Psoriasis is defined as a chronic inflammatory disease involving keratinocytes hyperproliferation of the epidermis with the acceleration in the epidermal turnover time, which is affected by various factors including genetic, immunologic, and environmental factors. There is a high risk for the development of premature cardiovascular diseases among patients with psoriasis as well as one of the life-threatening events is an aortic aneurysm (AA).

Case report

We report a 60-year-old man with the diagnosed psoriatic disease that an enlargement of the abdominal AA was incidentally found by annual check-up.

Conclusion

Further large-scale studies are needed to find the prevalence of abdominal AA in psoriasis and the appropriate screening time of that in this disease.

Long-term safety profile of ixekizumab in patients with moderate-to-severe plaque psoriasis: an integrated analysis from 11 clinical trials

BACKGROUND

Psoriasis in many patients is a chronic and recalcitrant disease that requires long-term treatment, reinforcing the importance of long-term safety data. Ixekizumab, a high-affinity monoclonal antibody that selectively targets interleukin (IL)-17A, is approved for treating patients with moderate-to-severe plaque psoriasis.

OBJECTIVE

To determine long-term safety of ixekizumab in psoriasis.

METHODS

Integrated safety data are presented from 12-week induction period, 12-60-week maintenance period, and from all ixekizumab-treated patients from 11 clinical studies. Exposure-adjusted incidence rates (IRs) per 100 patient-years are reported.

RESULTS

Overall, 5689 patients accounted for 12 061.5 patient-years of ixekizumab exposure from 11 studies. Over 156 weeks, a total of 83.9% (n = 4775) of patients reported treatment-emergent adverse events (AEs). Most opportunistic infections (IR [95% confidence interval; CI] 1.8 [1.6, 2.1]) reported were mucocutaneous candidiasis. The IR (95% CI) for oral Candida infection was 0.9 (0.8, 1.1). There was no trend of increase in IR of AEs of special interest. Serious AEs were reported in 11.8% of patients; death occurred in 0.4% (n = 23) of patients.

CONCLUSION

The 3-year, long-term maintenance treatment with ixekizumab did not show any new safety signals in patients with moderate-to-severe plaque psoriasis.

Effects of treatment for psoriasis on circulating levels of leptin, adiponectin and resistin: a systematic review and meta-analysis

BACKGROUND

Metabolic syndrome, a risk factor of cardiovascular disease, is more common in patients with psoriasis than in the general population. Circulating adipokine concentrations are altered in patients with psoriasis and are suggested to represent the pathophysiological link between psoriatic lesions and metabolic alterations.

OBJECTIVES

To perform a systematic review of the literature for studies that investigated possible differences in circulating levels of leptin, adiponectin or resistin in patients with psoriasis before and after any treatment intervention, and to meta-analyse the best evidence available.

METHODS

A search was conducted in three databases (PubMed, Central and Embase). Eligible for the review were studies that assessed leptin, adiponectin or resistin concentrations in patients with psoriasis before and after any topical or systemic treatment.

RESULTS

After treatment, blood concentrations of leptin were similar to those before treatment [standardized mean difference (SMD) 0·06, 95% confidence interval (CI) -0·09 to 0·20], with no heterogeneity among studies (I² = 0%, P = 0·88). After treatment, blood concentrations of adiponectin were similar to those before treatment (SMD -0·14, 95% CI -0·34 to 0·05), with significant heterogeneity among studies (I² = 36·8%, P = 0·032). After treatment, blood concentrations of resistin were significantly lower than those before treatment (SMD 0·50, 95% CI 0·20-0·79), with significant heterogeneity among studies (I² = 61·4%, P < 0·001).

CONCLUSIONS

There is no evidence that treatment for psoriasis modifies leptin and adiponectin concentrations. However, treatment intervention reduces resistin concentrations, a finding that is expected to be of clinical importance.

Association of Metabolic Syndrome in Chronic Plaque Psoriasis Patients and their Correlation with Disease Severity, Duration and Age: A Case Control Study from Western Maharashtra

INTRODUCTION

Psoriasis is a chronic systemic inflammatory disease where the skin and the joints are the primary targets. Despite the fact that psoriasis carries minimal risk of mortality, it is associated with significant morbidity which may have a significant impact on quality of life of patients. Globally, psoriasis has been reported to be associated with Metabolic Syndrome (MS) including obesity, dyslipidemia, diabetes and hypertension. Association of MS and its various components with psoriasis has been consistently reported in various studies, but there is a paucity of data on this association from the Indian subcontinent.

AIM

To compare the prevalence of MS in patients with psoriasis and controls and to determine association of MS with age of patient, severity and duration of psoriasis.

MATERIALS AND METHODS

A hospital based case control study on 95 psoriasis patients and 95 age and sex matched controls. MS was diagnosed by the presence of three or more of the South Asian Modified National Cholesterol Education Program's Adult Panel III SAM-NCEP criteria. Clinical, biometric and necessary laboratory evaluations were performed. Statistical analysis was performed by using Statistical Package for the Social Sciences (SPSS version 16.0). Data was compared between cases and controls using unpaired t-test and chi-square test and odds ratio with 95% confidence interval.

RESULTS

MS was significantly more common in psoriatic patients than in controls (38.9%vs 21.05%, odds ratio 2.39, 95% confidence interval, 1.26-4.55; p-value=0.007). Psoriatic patients had higher prevalence of hypertriglyceridemia (45.2%vs.11.5%), decreased HDL cholesterol (27.3%vs.4.2%), abdominal obesity (32.6% vs.15.7%) and elevated blood pressure (18.9%vs.5.2%) whereas no association observed for elevated blood sugar level (12.6%vs.5.2%). MS was present in psoriasis cohort irrespective of severity and duration of psoriasis. (p-value 0.123, 0.596 respectively). MS was more prevalent in elderly individuals with psoriasis (51.1%vs.28% p-value=0.008; Odds ratio 3.12, 95% confidence interval 1.32-7.35).

CONCLUSION

Significant association between psoriasis and MS was noted and it was independent of disease duration and severity. Elderly psoriatic patients were more prone for developing MS. We suggest that all patients of psoriasis, irrespective of disease, duration and severity, should be screened for MS to prevent significant morbidity and mortality associated with it.

Development and Validation of a Novel Questionnaire for Adherence with Topical Treatments in Psoriasis (QATOP)

BACKGROUND

Self-report measures are the most used methodologies for the evaluation of adherence to psoriasis topical treatment, although currently there is no standard questionnaire for this purpose.

OBJECTIVE

The present study aimed at developing a novel questionnaire (Questionnaire for Adherence to TOPical treatment [QATOP]) for the assessment of adherence to topical treatment in psoriasis.

METHODS

A questionnaire containing nine items organized into two parts (part 1: current patient treatment; part 2: adherence to treatment, amount used, and treatment-associated variables) was developed, supported by a systematic literature review, qualitative patient focus interviews, and expert-group input. Its content validity was determined by a pilot study of six patients. Adherence to topical treatment was then assessed in 35 patients with psoriasis, after 45 days of treatment, using the QATOP and a medication log. Associations between different items of the QATOP and the log were investigated.

RESULTS

Adherence results were 63.5 ± 29.2% for the log and 60.9 ± 24.4% for the QATOP, and were strongly correlated (R = 0.819, p < 0.001). Distinct posologic regimens were reported by patients, which, in some cases, were not the usual doses. Patients also reported using doses of medicine on each application that were markedly lower than required.

CONCLUSION

The QATOP is a valid and reliable self-report measure of adherence to topical treatment in patients with psoriasis. The use of this standard questionnaire could improve the methodological quality of adherence studies. Improvement of the clarity of posologic instructions is clearly urgently needed.

Randomized Placebo Control Study of Metformin in Psoriasis Patients with Metabolic Syndrome (Systemic Treatment Cohort)

BACKGROUND

Psoriasis has been found to be associated with obesity, metabolic syndrome (MS), diabetes, and cardiovascular risk factors. Metformin treatment showed improvement in cardiovascular risk factors and hyperinsulinemia.

OBJECTIVE

To evaluate the efficacy and safety of metformin in psoriasis patients with MS.

MATERIALS AND METHODS

This was a single-center, parallel-group, randomized, open-label study with blinded end point assessment of metformin (1000 mg once daily for 12 weeks; n = 20) and placebo (n = 18) in psoriasis patients with MS. Total sample size was 38 participants.

RESULTS

Statistically significant improvement was observed in mean percentage change in erythema, scaling, and induration (ESI) (P = 0.048) in metformin as compared to placebo while mean percentage change in psoriasis area and severity index (PASI) and physician global assessment (PGA) scores was not significant (PASI - P = 0.215, PGA - P = 0.070). There was a statistically significant difference in percentage of parameters of MS improved following 12 weeks of treatment in metformin (19%) as compared to placebo (8.9%) group (P = 0.046). Statistically significant difference in percentage of patients achieving 75% reduction in ESI scores (P = 0.024). Significant improvement was observed in mean weight, body mass index (BMI), total cholesterol, and low-density lipoprotein (LDL) cholesterol in metformin group as compared to placebo. Improvement in BMI, fasting plasma glucose, serum triglycerides, high-density lipoprotein, LDL, systolic blood pressure, diastolic blood pressure, and total cholesterol was statistically significant in metformin group over the period of 12 weeks. There was no significant difference in adverse events in two groups except weight gain.

CONCLUSION

Metformin has shown improvement in psoriasis and parameters of MS, hence can be used for the benefit of psoriasis patients having MS. Large, controlled studies are needed to confirm.

Review: the Multiple Roles of Monocytic Microparticles

Monocytic microparticles (mMP) are microparticles derived from human monocytes either under in vivo or in vitro conditions. The size of mMP is between 0.1 and 1.0 μm. Apart from the size range, mMPs are also identified based on phosphatidylserine and CD14 expression on their surface, though this is not always the case. Monocytic MP are critical players in inflammation, endothelial cell function, and blood coagulation. They exhibit dual function by either helping the progression of such conditions or limiting it, depending on certain factors. Furthermore, the numbers of mMP are elevated in some autoimmune diseases, infectious diseases, and metabolic disorders. However, it is unknown whether mMP play an active role in these diseases or are simply biomarkers. The mechanism of mMP modulation is yet to be identified. In this review, we highlight the mechanism of mMP formation and the roles that they play in inflammation, blood coagulation, and different disease settings.

Subclinical atherogenesis in patients with mild psoriasis: A role for IL-6?

Summary Introduction: A link of psoriasis with subclinical atherosclerosis has been postulated and cytokine network might intermediate this association. Few data are available in patients with mild psoriasis. We evaluated carotid intima-media thickness (cIMT) in drug-free psoriatic individuals and controls. In parallel, we searched for associations of cIMT with disease activity indexes and serum interleukins (IL) in psoriatic patients. Method: An experienced radiologist performed the cIMT analyses. Cytokine concentrations were assessed by flow cytometry. Disease activity was evaluated based on psoriasis area and severity index (PASI) as well as body surface area (BSA). Results: Sixty-five (65) patients and 64 controls were studied. Mean age of patients (50.9 years) did not differ from controls (p=0.362). A low PASI and BSA (< 10) prevailed (69.2% and 56.9%, respectively). Median levels of IL-12p70, TNF-α, IL-1β and IL-10 were significantly lower in cases than in controls (adjusted p<0.05), while IL-6 and IL-8 medians did not differ between groups (adjusted p>0.05). Smoking habit and diabetes mellitus predominated in cases (p=0.002). An altered cIMT (≥ 0.9 mm) was more frequent in cases than in controls (23.8% versus 8.5%, adjusted p=0.045). Mean cIMT was higher in cases with a borderline significance (p=0.057). cIMT scores did not correlate to PASI (rs=0.066; p=0.250) or BSA (rs=0.175; p=0.185), but did correlate significantly with serum IL-6 (rs=0.26; p=0.005). Conclusion: Subclinical atherosclerosis was more frequent in patients with mild psoriasis than controls. cIMT in psoriatic individuals correlated with serum IL-6, pointing to an eventual proatherogenic role of IL-6 in these patients. Newer studies should clarify the connection of atherogenesis with cytokines in psoriasis.

Acid-reducing vagotomy is associated with reduced risk of subsequent ischemic heart disease in complicated peptic ulcer: An Asian population study

Persistent exacerbation of a peptic ulcer may lead to a complicated peptic ulcer (perforation or/and bleeding). The management of complicated peptic ulcers has shifted from acid-reducing vagotomy, drainage, and gastrectomy to simple local suture or non-operative (endoscopic/angiographic) hemostasis. We were interested in the long-term effects of this trend change. In this study, complicated peptic ulcer patients who received acid-reducing vagotomy were compared with those who received simple suture/hemostasis to determine the risk of ischemic heart disease (IHD).This retrospective cohort study analyzed 335,680 peptic ulcer patients recorded from 2000 to 2006 versus 335,680 age-, sex-, comorbidity-, and index-year matched comparisons. Patients with Helicobacter pylori (HP) infection were excluded. In order to identify the effect of vagus nerve severance, patients who received gastrectomy or antrectomy were also excluded. The incidence of IHD in both cohorts, and in the complicated peptic ulcer patients who received acid-reducing vagotomy versus those who received simple suture or hemostasis was evaluated.The overall incidence of IHD was higher in patients with peptic ulcer than those without peptic ulcer (17.00 vs 12.06 per 1000 person-years), with an adjusted hazard ratio (aHR) of 1.46 based on multivariable Cox proportional hazards regression analysis controlling for age, sex, Charlson's comorbidity index, and death (competing risk). While comparing peptic ulcer patients with acid-reducing vagotomy to those with simple suture/hemostasis or those without surgical treatment, the aHR (0.58) was the lowest in the acid-reducing vagotomy group.Patients with peptic ulcer have an elevated risk of IHD. However, complicated peptic ulcer patients who received acid-reducing vagotomy were associated with reduced risk of developing IHD.

Randomized placebo control study of insulin sensitizers (Metformin and Pioglitazone) in psoriasis patients with metabolic syndrome (Topical Treatment Cohort)

Background

Increased prevalence of metabolic syndrome (MS) is observed in psoriasis. Metformin has shown improvement in cardiovascular risk factors while pioglitazone demonstrated anti proliferative, anti-inflammatory and anti angiogenic effects. Study objective is to evaluate the efficacy and safety of Insulin sensitizers (metformin and pioglitazone) in psoriasis patients with metabolic syndrome (MS).

Methods

Single centre, parallel group, randomized, study of metformin, pioglitazone and placebo in psoriasis patients with MS.

Results

Statistically significant improvement was observed in Psoriasis Area and Severity Index (PASI), Erythema, Scaling and Induration (ESI) and Physician global assessment (PGA) scores in pioglitazone (p values – PASI = 0.001, ESI = 0.002, PGA = 0.008) and metformin groups (p values – PASI = 0.001, ESI = 0.016, PGA = 0.012) as compared to placebo. There was statistically significant difference in percentage of patients achieving 75 % reduction in PASI and ESI scores in metformin (p value – PASI = 0.001, ESI = 0.001) and pioglitazone groups (p vaue – PASI = 0.001, ESI = 0.001). Significant improvement was observed in fasting plasma glucose (FPG) and triglycerides levels in metformin and pioglitazone arms. Significant improvement was noted in weight, BMI, waist circumference, FPG, triglycerides and total cholesterol after 12 weeks of treatment with metformin while pioglitazone showed improvement in FPG, triglyceride levels, systolic blood pressure (SBP), diastolic blood pressure (DBP), total cholesterol and LDL cholesterol levels. There was no difference in pattern of adverse drug reaction in three groups.

Conclusion

Insulin sensitizers have shown improvement in the parameters of MS as well as disease severity in psoriasis patients.

Primary care-based screening for cardiovascular risk factors in patients with psoriasis

Background

Studies assessing cardiovascular disease (CVD) risk factors in patients with psoriasis have been limited by selection bias, inappropriate controls or a reliance on data collected for clinical reasons.

Objectives

To investigate whether screening for CVD risk factors in patients with psoriasis in primary care augments the known prevalence of CVD risk factors in a cross‐sectional study.

Methods

Patients listed as having psoriasis in primary care were recruited, screened and risk assessed by QRISK2.

Results

In total, 287 patients attended (mean age 53 years, 57% women, 94% white British, 22% severe disease, 33% self‐reported psoriatic arthritis). The proportion with known and screen‐detected (previously unknown) risk factors was as follows: hypertension 35% known and 13% screen‐detected; hypercholesterolaemia 32% and 37%; diabetes 6·6% and 3·1% and chronic kidney disease 1·1% and 4·5%. At least one screen‐detected risk factor was found in 48% and two or more risk factors were found in 21% of patients. One in three patients (37%) not previously known to be at high risk were found to have a high (> 10%) 10‐year CVD risk. Among the participants receiving treatment for known CVD risk factors, nearly half had suboptimal levels for blood pressure (46%) and cholesterol (46%).

Conclusions

Cardiovascular risk factor screening of primary care‐based adults with psoriasis identified a high proportion of patients (i) at high CVD risk, (ii) with screen‐detected risk factors and (iii) with suboptimally managed known risk factors. These findings need to be considered alongside reports that detected limited responses of clinicians to identified risk factors before universal CVD screening can be recommended.

What's already known about this topic?

Several studies have suggested that patients with psoriasis have a greater number of risk factors for cardiovascular disease (CVD) and a higher risk for vascular events compared with the general population.

However, the prevalence data used to support systematic CVD risk factor screening in psoriasis have been limited by selection bias, inappropriate choice of control groups or reliance on risk factors measured for other clinical reasons.

What does this study add?

Cardiovascular risk factor screening of primary care‐based adults with psoriasis identified a high proportion of patients (i) at high CVD risk, (ii) with screen‐detected risk factors and (iii) with suboptimally managed known risk factors.

These findings need to be considered alongside reports that detected limited responses of clinicians to identified risk factors before universal CVD screening can be recommended.

Increased subsequent risk of erectile dysfunction among middle and old age males with chronic osteomyelitis: a nationwide population-based cohort study

Chronic inflammation may cause endothelial dysfunction and atherosclerosis, resulting in subsequent erectile dysfunction (ED). We examined the relationship between chronic osteomyelitis, which is a chronic inflammatory disease, and ED. A retrospective cohort study was conducted using data from the National Health Insurance Research Database. After excluding patients <40 years of age, 677 male patients newly diagnosed with chronic osteomyelitis (COM) from 1 January 2000 to 31 December 2011 were identified for the study. The non-osteomyelitis comparison cohort consisted of 2706 male participants. The incidence of ED was 2.66-fold higher in the COM cohort than in the non-osteomyelitis cohort (4.01 vs 1.51 per 10 000 person-years). After adjusting for age and comorbidities of coronary heart disease, hypertension, hyperlipidemia, depression, stroke, diabetes, peripheral vascular disease, chronic kidney disease, chronic obstructive pulmonary disease and asthma, the patients with COM had a 2.82-fold risk of ED (95% confidence interval=1.44-5.56). The incidence of ED increased with that of comorbidities in both cohorts. The highest hazard ratio was in patients between 40 and 59 years of age who had COM. Our data showed, for the first time, that COM is a possible risk factor for the development of ED.

Inflammatory and Lipid-Associated Markers of Cardiovascular Diseases in Children with First Exacerbation of Inflammatory Bowel Disease

Background

Adult patients with inflammatory bowel disease (IBD) are at increased risk of early atherosclerosis and atherosclerosis-driven cardiovascular diseases. However, data on the development of early, subclinical atherosclerosis in children with IBD are scarce. The aim of this study was to assess selected biomarkers of atherosclerosis in children with IBD.

Material/Methods

The study group comprised 30 children with first exacerbation of IBD. Twenty healthy children were enrolled into the control group. Total cholesterol, triglycerides, low-density lipoproteins (LDL), high-density lipoproteins (HDL), lipoprotein (a) (Lp(a)), interleukin 6 (Il-6), high sensitivity C-reactive protein (hs-CRP), and oxidized LDL (ox LDL) were determined.

Results

There were no significant differences in lipids profiles in IBD children and controls. Mean IL-6 level (8.996 pg/ml) was significantly higher in the IBD group compared to controls (3.502 pg/ml). Mean hs-CRP concentration was significantly higher in IBD children than in controls (7.648 and 1.290 μg/ml, respectively). In the IBD group, mean ox-LDL concentration (144.837 ng/ml) was lower than in controls (162.352 ng/ml), but the difference was non-significant (P=0.4). Mean Lp(a) serum level was higher in patients with IBD (19.418 mg/dl) than in controls (10.970 mg/dl), but it was also non-significant.

Conclusions

No significant differences were found in biomarkers of atherosclerosis in children with IBD compared to controls. Elevated IL-6 and hs-CRP level are well-established inflammatory markers. Further studies are needed to fully determine cardiovascular risk factors in IBD children.

Growth arrest-specific 6 and cardiometabolic risk factors in patients with psoriasis

OBJECTIVES

An increased risk for cardiovascular disease with psoriasis has been reported. Growth Arrest-Specific 6 (GAS6) amplifies pro-inflammatory endothelial cell activation via TAM receptors. However, it also inhibits inflammation by multiple mechanisms including phagocytosis. The objective of this study was to investigate whether plasma GAS6 levels are associated with conventional cardiometabolic (CM) risk factors in patients with psoriasis.

METHODS

Forty patients diagnosed with psoriasis (22 male, mean age: 43.3 ± 13.8 years) and 40 age-/sex-matched healthy controls (22 male, mean age: 39.3 ± 8.9 years) were included in the study. CM risk factors (hypertension, hyperlipidemia, diabetes mellitus, and cigarette smoking) were identified. GAS6 levels were measured by ELISA.

RESULTS

There were no significant differences between the plasma GAS6 levels of patients with psoriasis compared to the control group (6.6 ± 2.0 ng/mL, 7.6 ± 2.8 ng/mL, respectively, P > 0.05). However, GAS6 levels of patients with psoriasis having a smoking history (n = 11) were significantly lower than both patients with psoriasis who had no smoking history (n = 29) and controls (5.5 ± 1.7 ng/mL, 6.9 ± 1.9 ng/mL, 7.6 ± 2.8 ng/mL, respectively, P < 0.05). Similarly, psoriasis patients with at least one CM risk factor showed lower GAS6 levels compared to subjects without any CM risk factor (5.7 ± 1.7 ng/mL, 7.3 ± 2.0 ng/mL, P < 0.01). There was no correlation between the GAS6 level, disease duration or PASI score (r = 0.150, -0.150, and P = 0.310, 0.398, respectively).

CONCLUSIONS

This pilot study provides the first evidence in humans for an association between low plasma GAS6 levels and conventional risk factors in psoriasis. Further large scale, prospective studies are needed to confirm these results.

A multileveled approach in psoriasis assessment and follow-up: A proposal for a tailored guide for the dermatological practice

BACKGROUND

Psoriasis is a complex and heterogeneous disease resulting from interactions between genetic, immunological, and environmental factors. To make the most optimal treatment decision, the dermatologist must therefore have a detailed overview of the patient's history and lifestyle.

OBJECTIVES

We sought to offer an overview of the various relevant aspects in clinical dermatological assessment of psoriasis patients, emphasizing the importance of a multidisciplinary and integrated clinical approach.

METHODS

We gathered information on psoriasis management and developed a tailored checklist covering all health-related aspects associated with psoriasis.

RESULTS

Demographics, personal and family history were elaborately described as well as drug history to discuss how they affect psoriasis management. Relevant patient information such as the vaccination status or cardiovascular profile were included in the checklist as well and treatment recommendations were adapted and updated in accordance with evidence-based literature. This checklist also emphasizes the importance of drug surveillance, proper follow-up and specialist referral, and why the dermatologist needs to address these health-related aspects when assessing psoriasis patients, going beyond optimal skin care.

CONCLUSIONS

Our comprehensive overview can be used as a consultation checklist for good clinical practice in psoriasis patient management and aid in treatment decision.

Increased Prevalence of Coronary Artery Disease in Severe Psoriasis and Severe Atopic Dermatitis

BACKGROUND

Psoriasis and atopic dermatitis (AD) are immuno-inflammatory diseases that can result in lifelong systemic inflammation. Unlike AD, psoriasis has been associated with cardiovascular disease. The aim of this study was to examine the prevalence, severity, and subtype of coronary artery disease (CAD) in psoriasis and AD patients without known cardiovascular disease.

METHODS

Consecutively enrolled patients (psoriasis n = 58, AD n = 31) and retrospectively matched controls (n = 33) were examined using cardiac computed tomography angiography (CCTA) and assessed using an 18-segment model of the coronary tree.

RESULTS

The prevalence of a coronary artery calcium score >0 was 29.8% in psoriasis and 45.2% in AD, vs 15.2% in controls (P = .09 and P = .01, respectively). More patients with psoriasis had a coronary artery calcium score ≥100 (psoriasis 19.3%, controls 2.9%; P = .02). CCTA showed the presence of plaques in 38.2% of psoriasis patients and 48.1% of AD patients, vs 21.2% of controls (P = .08 and P = .03, respectively). Psoriasis was associated with an increased prevalence of significant coronary stenosis (stenosis >70%) (psoriasis 14.6%, controls 0%; P = .02) and 3-vessel coronary affection or left main artery disease (psoriasis 20%, controls 3%; P = .02), whereas AD was associated with mild (AD 40.7%, controls 9.1%; P = .005) single-vessel affection.

CONCLUSIONS

These findings suggest that psoriasis and AD are associated with an increased prevalence of CAD. Patients with psoriasis have an increased prevalence of severe CAD.

Blood lipid levels associate with childhood asthma, airway obstruction, bronchial hyperresponsiveness, and aeroallergen sensitization

BACKGROUND

Studies of children's blood lipid profiles in relation to asthma are few, and the results are ambiguous.

OBJECTIVE

We sought to examine whether the lipid profile is associated with concurrent asthma, altered lung function, and allergic sensitization in children.

METHODS

High-density lipoprotein cholesterol, low-density lipoprotein cholesterol, and triglyceride levels were measured at ages 5 to 7 years in the Copenhagen Prospective Studies on Asthma in Childhood2000 at-risk birth cohort. Asthma and allergic rhinitis were diagnosed based on predefined algorithms at age 7 years along with assessments of lung function, bronchial responsiveness, fraction of exhaled nitric oxide (Feno), and allergic sensitization. Associations between lipid levels and clinical outcomes were adjusted for sex, passive smoking, and body mass index.

RESULTS

High levels of low-density lipoprotein cholesterol were associated with concurrent asthma (adjusted odds ratio [aOR], 1.93; 95% CI, 1.06-3.55; P = .03) and airway obstruction: 50% of forced expiratory flow (aβ coefficient, -0.13 L/s; 95% CI, -0.24 to -0.03 L/s; P = .01) and specific airway resistance (aβ coefficient, 0.06 kPa/s; 95% CI, 0.00-0.11 kPa/s; P = .05). High levels of high-density lipoprotein cholesterol were associated with improved specific airway resistance (aβ coefficient, -0.11 kPa/s; 95% CI, -0.21 to -0.02; P = .02), decreased bronchial responsiveness (aβ coefficient, 0.53 log-μmol; 95% CI, 0.00-1.60 log-μmol; P = .05), decreased risk of aeroallergen sensitization (aOR, 0.27; 95% CI, 0.01-0.70; P = .01), and a trend of reduced Feno levels (aβ coefficient, -0.22 log-ppb; 95% CI, -0.50 to 0.01 log-ppb; P = .06). High triglyceride levels were associated with aeroallergen sensitization (aOR, 2.01; 95% CI, 1.14-3.56; P = .02) and a trend of increased Feno levels (aβ coefficient, 0.14 log-ppb; 95% CI, -0.02 to 0.30 log-ppb; P = .08).

CONCLUSION

The blood lipid profile is associated with asthma, airway obstruction, bronchial responsiveness, and aeroallergen sensitization in 7-year-old children. These findings suggest that asthma and allergy are systemic disorders with commonalities with other chronic inflammatory disorders.

Increased risk of ischaemic stroke among patients with multiple sclerosis

BACKGROUND AND PURPOSE

Inflammatory processes including autoimmune diseases which ignite endothelial dysfunction and atherosclerosis may promote development of cardiovascular diseases including ischaemic stroke. This study aimed to evaluate whether multiple sclerosis (MS) increases stroke risk.

METHODS

A national insurance claim data set of 22 million enrollees in Taiwan was used to identify 1174 patients with MS and 4696 randomly selected age- and gender-matched controls from 1 January 1997 to 31 December 2010. Both cohorts were followed up until the occurrence of stroke or censor. Relevant covariates, such as age, gender, hypertension, diabetes, hyperlipidaemia, coronary artery disease, congestive heart failure and pregnancy, were included for further survey. The hazard ratio (HR) of stroke was assessed using a Cox proportional hazards regression model.

RESULTS

After adjusting for the relevant covariates, the MS cohort had an increased risk of stroke (adjusted HR = 12.1 for 1 year; adjusted HR = 4.69 for 2-5 years) compared with the control cohort within 5 years of follow-up. Amongst participants without comorbidities, the MS cohort was still at a greater stroke risk than the control cohort [HR 4.93, 95% confidence interval (CI) 2.85-8.55]. Moreover, in the population aged ≤40, MS was associated with a significantly increased risk of stroke (HR 12.7, 95% CI 3.44-46.7).

CONCLUSIONS

Multiple sclerosis is declared to be associated with an increased risk in developing stroke, which requires closer attention to this group of patients for stroke prevention, especially in the younger population.

Association between psoriasis and coronary calcium score

BACKGROUND

Emerging data suggests that chronic inflammatory disease, such as psoriasis, may be associated to coronary artery disease (CAD).

OBJECTIVE

Analyze the association between psoriasis and subclinical atherosclerosis using coronary calcium score (CAC).

METHODS

We investigated 221 participants with psoriasis and 718 age- and sex-matched controls without prior known CAD. All participants completed a questionnaire and underwent laboratory tests and a CAC exam. Logistic regression models adjusted for Framingham risk score (FRS) and C-reactive protein (hs-CRP) were built. CAC was included in the models as a binary variable with different cut off values.

RESULTS

Body-mass index, race, hypertension, HDL, LDL and hs-CRP were significantly associated with psoriasis presence and severity. Psoriasis severity was significantly associated with CAC (p = 0.04), particularly for very high CAC (>400) (p < 0.01). The OR for severe psoriasis and CAC >400 was 2.45 (95%CI: 1.26-4.75) in unadjusted models. In a model adjusted for the FRS, this association was no longer significant, but a trend was noted (p = 0.09). No significant changes in the association were noted after the inclusion of hs-CRP in the model.

CONCLUSION

Psoriasis is associated with higher CAC values, mainly in individuals with severe psoriasis. The current findings also suggest the potential involvement of other mechanisms beyond classical cardiovascular risk factors and inflammation in this association.

Risk of cardiovascular disease in inflammatory bowel disease

Abundant scientific evidence supporting an association between inflammatory bowel disease (IBD) and venous thromboembolic events, caused by an IBD related hypercoagulability, is acknowledged and thromboprophylactic treatment strategies are now implemented in the management of IBD patients. In contrary, the risk of arterial thromboembolic disease, as ischemic heart disease, cerebrovascular events, and mesenteric ischemia in patients with IBD remains uncertain and the magnitude of a potentially increased risk is continuously debated, with ambiguous risk estimates among studies. The evident role of inflammation in the pathogenesis of atherosclerosis forms the basis of a biological plausible link; the chronic systemic inflammation in IBD patients increases the risk of atherosclerosis and thereby the risk of thrombotic events. Further, studies have shown that the burden of traditional risk factors for atherosclerosis, such as obesity, diabetes mellitus, and dyslipidemia is lower in IBD populations, thus further strengthen the role of non-traditional risk factors, as chronic inflammation in the linking of the two disease entities. Likewise, mortality from cardiovascular disease in IBD remains questioned. The aim of the current review is to give an up-date on the existing evidence of the possible association between IBD and cardiovascular disease and to discuss traditional and non-traditional risk factors.

Increased prevalence of psoriasis in patients with coronary artery disease: results from a case-control study

BACKGROUND

The incidence of myocardial events has been reported to be increased in patients with psoriasis.

OBJECTIVES

To investigate whether psoriasis is an independent risk factor for coronary artery disease (CAD).

METHODS

We compared the prevalence of psoriasis between case patients with a diagnosis of CAD based on coronary angiography findings and control patients with no CAD referred to the emergency surgery department for an acute noncardiovascular condition. Case and control patients were examined for the presence of psoriasis by two dermatologists. The prevalence of psoriasis was compared among patients with CAD according to CAD severity. Five-hundred cases and 500 age- and sex-matched controls were included.

RESULTS

Using matched univariate analysis, the prevalence of psoriasis was about twofold higher in CAD case patients than in control patients [8·0% vs. 3·4%, odds ratio (OR) 2·64; 95% confidence interval (CI) 1·42-4·88]. Using unconditional multivariate analysis, the association of psoriasis with CAD appeared to be borderline significant (OR 1·84; 95% CI 0·99-3·40). Psoriasis in patients with CAD was significantly associated with three-vessel involvement relative to one-or two-vessel involvement (13·1% vs. 6·1%; OR 3·07; 95% CI 1·50-6·25).

CONCLUSIONS

The prevalence of psoriasis is twofold higher in patients with CAD than in control patients without CAD. It is associated with a more severe coronary artery involvement.

Cardiovascular disease in psoriatic post-menopausal women

BACKGROUND

It is generally accepted that the risk of cardiovascular disease (CVD) in women is significantly increased after the menopause. Hormonal changes associated with the menopausal transition may also alter the course of autoimmune diseases. It has been reported that menopause may exacerbate the symptoms of rheumatoid arthritis, systemic sclerosis and giant cell arteritis, but attenuate the course of systemic lupus erythemathosus. There is a growing body of literature indicating that the course of psoriasis may be altered by menopausal hormone changes. Considering the fact that both psoriasis and menopause are independent risk factors for CVD, and that menopause may exacerbate the course of psoriasis, a possible additive effect between these two conditions may be crucial for proper monitoring and treatment of peri- and post-menopausal psoriatic patients.

OBJECTIVE

The aim of this study is to analyse potential relationship between psoriasis, menopausal status and risk of CVD.

MATERIALS AND METHODS

A retrospective analysis of the Clalit Health Services database was performed in an attempt to provide new data and the available literature concerning these issues was reviewed. Data on cardiovascular events in 10 872 female psoriatic patients and 19 471 controls were extracted and compared.

RESULTS

In both psoriatic and control patients the association of CVD increased with age. The association of CVD was significantly greater in psoriatic patients, but no significant differences were found between any of age groups.

CONCLUSIONS

The association of psoriasis and CVD in women increases with age but there is insufficient evidence to confirm that menopause increases the risk of psoriasis. Further studies directly addressing this issue are needed.

Cardiometabolic biomarkers in chronic plaque psoriasis before and after etanercept treatment

OBJECTIVE

To assess cardiometabolic biomarkers in patients with psoriasis before and after etanercept treatment.

METHODS

Patients with moderate-to-severe plaque psoriasis were randomized to etanercept 50 mg once or twice weekly, double-blinded. Cardiometabolic biomarkers were assessed at baseline and after 12 weeks of treatment (n = 273).

RESULTS

At baseline, 42% of patients had metabolic syndrome. Etanercept was not associated with any clinically relevant adverse effects on cardiometabolic biomarkers. In the once-weekly subgroup, significant mean percentage changes from baseline (p < 0.05) were observed for the quantitative insulin-sensitivity check index (QUICKI; -2.2%), apolipoprotein (Apo) A1 (3.2%), Apo B:Apo A1 ratio (-3.5%), leptin (8.6%) and high-sensitivity C-reactive protein (hsCRP) (-65.5%); and in the twice-weekly subgroup for plasma insulin (15.9%), QUICKI (-2.7%), high-density lipoprotein cholesterol (HDL-C; 2.9%), apolipoprotein (Apo) A1 (2.8%), Apo B:Apo A1 (-4.6%) and hsCRP (-74.4%).

CONCLUSION

Metabolic syndrome was common in these patients with moderate-to-severe psoriasis. Etanercept treatment may provide some potentially favorable modulation of insulin sensitivity, HDL-C, Apo A1 and Apo B:Apo A1 ratio.

Impact of effective tumor necrosis factor-alfa inhibitor treatment on arterial intima-media thickness in psoriasis: results of a pilot study

BACKGROUND

Psoriasis is associated with higher incidence of atherosclerotic comorbidities. Sustained arterial wall inflammation mediated by common cytokines of psoriasis and atherogenesis precedes atherosclerotic plaque development. Increased intima-media thickness (IMT) is an accepted indicator of subclinical atherosclerosis and has been reported in severe psoriasis.

OBJECTIVE

This pilot study aimed to clarify whether effective long-term tumor necrosis factor-alfa inhibition decreases IMT in psoriasis.

METHODS

In 16 patients with severe psoriasis, the Psoriasis Area and Severity Index score was calculated before therapy (etanercept, infliximab, adalimumab) and after 6-month treatment. Simultaneously, carotid and brachial IMT was measured by high-resolution, B-mode ultrasonography. Difference between initial and 6-month IMT values was determined for monitored arteries collectively and separately in carotid and brachial arteries.

RESULTS

All of 16 patients achieved Psoriasis Area and Severity Index 75, and 14 of 16 achieved Psoriasis Area and Severity Index 90 improvement. In the group of patients without initial calcified atherosclerotic plaques (13 of 16) significant IMT decrease was detected when arteries were measured collectively (P = .0002). Initial and follow-up data differed significantly also at individual analysis of carotid (P = .011) and brachial (P = .006) arteries. Eleven of 13 patients had initial carotid IMT exceeding age-adjusted normal values. The other group (3 of 16) with initial manifest plaques showed increasing IMT tendency. Their baseline ultrasonography revealed carotid IMT above the upper limit of healthy adults' age-adjusted values.

LIMITATIONS

Study limitation involves small patient numbers, self-controlled study design, and lack of patients' stratification according to common cardiovascular risk factors.

CONCLUSION

In our pilot study effective tumor necrosis factor-alfa inhibition was found to decrease IMT in psoriatic patients without irreversible atherosclerotic plaques. Further analysis is recommended to confirm and complete our primary observations.

Long-term safety of ustekinumab in patients with moderate-to-severe psoriasis: final results from 5 years of follow-up

BACKGROUND

Long-term safety evaluations of biologics are needed to inform patient management decisions.

OBJECTIVES

To evaluate the safety of ustekinumab in patients with moderate-to-severe psoriasis treated for up to 5 years.

METHODS

Safety data were pooled from four studies of ustekinumab for psoriasis. Rates of adverse events (AEs), serious AEs (SAEs) and AEs of interest [infections, nonmelanoma skin cancers (NMSCs), other malignancies and major adverse cardiovascular events (MACE)] per 100 patient-years (PY) of follow-up were analysed by ustekinumab dose (45 or 90 mg) and by year of follow-up (years 1-5) to evaluate the dose response and impact of cumulative exposure. Observed rates of overall mortality and other malignancies were compared with those expected in the general U.S. population.

RESULTS

Analyses included 3117 patients (8998 PY) who received one or more doses of ustekinumab, with 1482 patients treated for ≥4 years (including 838 patients ≥5 years). At year 5, event rates (45 mg, 90 mg, respectively) for overall AEs (242·6, 225·3), SAEs (7·0, 7·2), serious infections (0·98, 1·19), NMSCs (0·64, 0·44), other malignancies (0·59, 0·61) and MACE (0·56, 0·36) were comparable between dose groups. Year-to-year variability was observed, but no increasing trend was evident. Rates of overall mortality and other malignancies were comparable with those expected in the general U.S. population.

CONCLUSIONS

No dose-related or cumulative toxicity was observed with increasing duration of ustekinumab exposure for up to 5 years. Rates of AEs reported in ustekinumab psoriasis trials are generally comparable with those reported for other biologics approved for the treatment of moderate-to-severe psoriasis.

Psoriasis and Cardiovascular Risk: Assessment by CUORE Project Risk Score in Italian Patients

Background. Psoriasis is a common inflammatory and immune-mediated skin disease. There is growing controversy as to whether cardiovascular risk is elevated in psoriasis. A number of studies suggest a high prevalence of cardiovascular risk factors as well as cardiovascular diseases in psoriasis patients. Objective. The objective of this study was to estimate cardiovascular risk score in psoriasis patients and the relation between cardiovascular risk and psoriasis features. Cardiovascular risk was assessed by CUORE project risk score built within the longitudinal study of the Italian CUORE project and suited to populations with a low rate of coronary heart disease. Results. A case-control study in 210 psoriasis outpatients and 111 controls with skin diseases other than psoriasis was performed. CUORE project risk score was higher in patients than controls (6.80 ± 6.34 versus 4.48 ± 4.38, P < 0.001). Compared to controls, psoriasis patients have higher risk of developing major cardiovascular events. Cardiovascular risk was not related to psoriasis characteristics. Conclusion. Increased focus on identifying cardiovascular risk factors and initiation of preventive lifestyle changes or therapeutic interventions in patients with psoriasis is warranted.

Hit hard and early: Can the march of psoriasis be halted?

Psoriasis is increasingly considered a systemic disease with comorbidities. There is sufficient evidence that systemic inflammation lies at the heart of these developments. Considering the chronic nature of psoriasis and its comorbidities, timely manipulation of systemic inflammation could avert both mortality and morbidity. Data from retrospective studies suggest that aggressive treatment of psoriasis with traditional systemic agents and/or biologic drugs improves health outcomes. To maximize treatment outcomes, severe psoriasis needs to be managed as a systemic disease with likely comorbidities.
